What's Wrong?

During a session, I received a notification to update my Git installation (Windows11). After completion, the current session of claude code broke with these messages

Skipping command-line '"C:\Program Files\Git\bin\..\usr\bin\bash.exe"'
('C:\Program Files\Git\bin\..\usr\bin\bash.exe' not found)
Need a valid command-line; Edit the string resources accordingly
This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason:
Error: Command failed: cygpath -u '*******WORKINGPATH*******'
Skipping command-line '"C:\Program Files\Git\bin\..\usr\bin\bash.exe"'
('C:\Program Files\Git\bin\..\usr\bin\bash.exe' not found)

What Should Happen?

Claude should handle this without breaking the session
